Problems solved by technology
However, the average length of the underground comprehensive pipe gallery is tens of kilometers, and it has hundreds of partitions. Each partition contains four cabins, and each cabin contains several types of equipment. How to deal with various alarms in the pipe gallery in a timely manner and carry out corresponding linkage becomes Solved the problem of the monitoring system of the underground comprehensive utility corridor
[0003] The traditional method mainly obtains the alarm situation of a single device, and judges a single alarm signal. When an alarm occurs, corresponding linkage is performed (alarm information display, video screen pops up, related equipment control commands are issued, etc.). When multiple alarms occur, Alarm judgment is performed through different thread scripts, and weight distribution is carried out to realize linkage processing. The alarm trigger mechanism is complicated and takes up a lot of resources.

Embodiment Construction
[0017] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.
[0018] Due to the large amount of monitoring data, many alarm signals, many control devices, and complex linkage mechanism of the underground comprehensive pipe gallery, the monitoring system of the underground comprehensive pipe gallery needs to have an efficient linkage trigger mechanism for the alarm signal of the underground comprehensive pipe gallery. The traditional alarm signal linkage trigger The main disadvantages of the method are:
[0019] When a large-scale alarm occurs, there are many types of alarm signals, and the linkage processing actions tha...

The invention discloses an alarm signal linkage triggering system and method for an underground comprehensive utility gallery monitoring system. The system includes a marker establishment module for establishing markers and initializing storage variables; an alarm variable acquisition module for acquiring alarm variables; The state judgment module is used to judge the state of all alarm variables. If an alarm occurs, it is 1, and if no alarm occurs, it is 0, and a binary number m is generated to store the alarm information in the pipeline corridor; the execution module is used to pass the binary number and Perform bit operation on each item in the flag bit, if the operation result is not 0, the alarm linkage script will be executed, if the operation result is 0, it will not be executed. The invention optimizes the alarm triggering efficiency and time of the monitoring system for the underground comprehensive utility gallery, reduces the program pressure, and improves the stability and reliability of the monitoring system for the underground comprehensive utility gallery.
Description
technical field [0001] The invention belongs to the field of monitoring of urban underground comprehensive utility corridors, and relates to an alarm signal linkage triggering system and method, in particular to an alarm signal linkage triggering system and method for an underground comprehensive utility corridor monitoring system. Background technique [0002] With the construction of the underground comprehensive pipe gallery, important pipelines such as natural gas pipelines, tap water pipes, sewage pipes, high-voltage cables, and optical fibers in the city enter the underground comprehensive pipe gallery, and the underground comprehensive pipe gallery has become the "lifeline" of the city. The safety and stability of the corridor are also very important. Through modern Internet of Things, big data and other technologies, an underground integrated utility corridor monitoring system is established to monitor the environmental conditions, equipment information, and video sig...
